“[President Obama’s] failed to make the case that a short, limited military campaign would promote our vital interests and our national security,” Cornyn said in a speech today on the Senate floor. “He's failed to lay out clear and realistic objectives that could be attained through the use of that military force. And he's failed to offer a compelling description of how his proposed intervention would advance America's broader foreign policy strategy - indeed, how it would advance his own policy of regime change.”
